Embodiment Construction
[0025] Embodiments of implementing the solid welding wire (hereinafter referred to as welding wire) of the present invention will be described in detail.
[0026] Even if the welding wire has the same composition, and even if the welding wire is produced by the same manufacturing method, when these welding wires are supplied to welding, the easiness of straightening the welding wire varies and the arc stability varies due to the difference in the manufacturing lot of the welding wire. Therefore, when the cross-sections of these welding wires were examined in detail, it was found that inclusions exist in the cross-sections of the original wires of the welding wires, and the inclusions significantly affect the easiness of straightening of the welding wires.
[0027] The welding wire of the present invention, based on the total mass of the welding wire, contains C: not less than 0.02% by mass and not more than 0.20% by mass, Si: not more than 1.0% by mass, Mn: not less than 0.8% b...
